Wrong. There are no 'majority consensus' against 'bixonimania' because they made it up, that was the point. It's unsurprisingly easy to get LLMs to repeat the only source on a term never before seen. This usually works; made-up neologisms are the fruitfly of data poisoning because it is so easy to do and so unambiguous where the information came from. (And retrieval-based poisoning is the very easiest and laziest and most meaningless kind of poisoning, tantamount to just copying the poison into the prompt and asking a question about it.) But the problem with them is that also by definition, it is hard for them to matter; why would anyone be searching or asking about a made-up neologism? And if it gets any criticism, the LLMs will pick that up, as your link discusses. (In contrast, the more sources are affected, the harder it is to assign blame; some papermills picked up 'bixonimania'? Well, they might've gotten it from the poisoned LLMs... or they might've gotten it from the same place the LLMs did which poisoned their retrievals, Medium et al.)
